AMD Radeon RX 7400 vs Lisuan Tech LX 7G100 Comparison

The Verdict

The recorded data presents a stark contrast between two GPUs that share a process node but little else. The AMD Radeon RX 7400 has a full set of benchmark results, while the Lisuan Tech LX 7G100 has no recorded benchmark scores, no average score, and no rival comparisons. The database lists the RX 7400 at the 17th percentile among all GPUs, with an average benchmark score of 2467. The LX 7G100 sits at the 50th percentile, which is a percentile ranking without supporting measurements. The data indicates that the RX 7400 is a low-power, entry-level part with measurable performance, while the LX 7G100 is a higher-specification card whose actual performance remains unquantified in the database.

The verdict from the available data is straightforward: the RX 7400 is the only one of the two with verified performance numbers. Its nearest rivals in the database include the AMD Radeon 8040S with an average score of 2440 (1.1% difference) and the NVIDIA GeForce 710M with an average score of 2433 (1.4% difference). These deltas show the RX 7400 sits in a tight cluster of low-end GPUs. The LX 7G100, despite having no benchmark data, has a substantially larger specification footprint: 12 GB of memory versus 8 GB, a 192-bit bus versus 128-bit, 6144 shading units versus 1792, and an FP32 throughput of 24.58 TFLOPS versus 16.49 TFLOPS. The data cannot confirm whether those specifications translate into superior performance, because no measurements exist. Users who require verified results should rely on the RX 7400. Users who prioritize raw specification counts and are willing to accept unverified performance should consider the LX 7G100, but the database provides no evidence of its real-world behavior.

Architecture Differences

The two GPUs share a 6 nm process node from TSMC, but their architectures diverge completely. The AMD Radeon RX 7400 uses the Navi 33 chip, built on RDNA 3.0 architecture with the codename Hotpink Bonefish. It belongs to the Navi III generation (RX 7000 series) and has a die size of 204 mm² with 13,300 million transistors, yielding a transistor density of 65.2 million per mm². The Lisuan Tech LX 7G100 uses the 7G106 chip with an architecture listed as TrueGPU. Its transistor count and die size are unknown, and it has no codename or series designation. The LX 7G100 belongs to the 7G100 generation, and its production status is Active.

The RX 7400 has 1792 shading units, 112 texture mapping units, and 64 raster output pipelines. It includes 28 ray tracing cores, which are absent from the LX 7G100's specification list. The LX 7G100 has 6144 shading units, 192 texture mapping units, and 96 raster output pipelines, but no ray tracing cores are listed. The FP32 compute rating for the RX 7400 is 16.49 TFLOPS, while the LX 7G100 reaches 24.58 TFLOPS. FP16 performance follows the same ratio: the RX 7400 delivers 32.97 TFLOPS (2:1), and the LX 7G100 delivers 49.15 TFLOPS (2:1). Pixel rate favors the LX 7G100 at 192.0 GPixel/s against 147.2 GPixel/s for the RX 7400. Texture rate also favors the LX 7G100 at 384.0 GTexel/s versus 257.6 GTexel/s.

API support shows both cards support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RX 7400 supports Vulkan 1.4, while the LX 7G100 supports Vulkan 1.3. The RX 7400 uses PCIe 4.0 x8, while the LX 7G100 uses PCIe 4.0 x16, giving the latter twice the interface width. Display outputs differ: the RX 7400 has 1x HDMI 2.1a and 3x DisplayPort 2.1, while the LX 7G100 has 4x DisplayPort 1.4a. The LX 7G100 has no HDMI output, which could matter for certain display setups.

Where Each One Wins

The RX 7400 wins in the only category where the database holds direct measurements: actual benchmark results. It has eight recorded scores across DirectX 9, 10, 11, 12, 3DMark Steel Nomad, G2D, G3D, and GPU compute tests. The LX 7G100 has zero benchmark entries. In terms of verified data, the RX 7400 is the clear winner. Its Passmark G3D score of 11897 and GPU compute score of 5152 provide concrete reference points, even though its 17th percentile ranking places it among the lower tier of all GPUs.

The LX 7G100 wins on paper in nearly every specification category. It has more memory (12 GB versus 8 GB), a wider memory bus (192-bit versus 128-bit), higher memory bandwidth (432.0 GB/s versus 288.0 GB/s), more shading units, more texture units, more raster operations pipelines, higher pixel rate, higher texture rate, and higher FP32 and FP16 throughput. Its TDP of 225 W is substantially higher than the RX 7400's 43 W, and its suggested power supply is 550 W versus 200 W. The LX 7G100 also has a larger physical footprint: 294 mm in length, 120 mm in height, and 49 mm in width, while the RX 7400's dimensions are not recorded. The RX 7400 uses a single 6-pin power connector, while the LX 7G100 uses a single 8-pin connector.

The use-case split follows the data. For workloads where verified performance is required, such as comparing against known rivals or estimating frame rates from established benchmarks, the RX 7400 is the only choice with supporting evidence. For workloads that demand high memory capacity, wide memory interfaces, and massive compute throughput, the LX 7G100's specifications suggest it is designed for heavier tasks, but the database contains no confirmation. The RX 7400's low 43 W TDP and 200 W suggested PSU indicate it suits compact, low-power systems. The LX 7G100's 225 W TDP and 550 W suggested PSU indicate it requires a robust power delivery system.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the RX 7400 and the LX 7G100, and no wins are recorded for either GPU. The comparison must therefore rely on the RX 7400's individual benchmark scores against the LX 7G100's complete lack of measurements.

The RX 7400's strongest recorded result is its Passmark G3D score of 11897, which represents its overall graphics performance in the Passmark suite. Its Passmark G2D score of 1209 covers 2D workloads. The DirectX 9 score of 176 is the highest among its DirectX tests, followed by DirectX 11 at 97, DirectX 10 at 59, and DirectX 12 at 44. The 3DMark Steel Nomad DX12 score is 1103. The GPU compute score is 5152.

The LX 7G100 has no equivalent numbers. Its specification sheet suggests it should outperform the RX 7400 in compute-heavy tasks: its 24.58 TFLOPS FP32 rating is roughly 49% higher than the RX 7400's 16.49 TFLOPS. Its memory bandwidth of 432.0 GB/s is exactly 1.5 times the RX 7400's 288.0 GB/s. Its pixel rate of 192.0 GPixel/s is about 30% higher than 147.2 GPixel/s. Its texture rate of 384.0 GTexel/s is about 49% higher than 257.6 GTexel/s. These deltas come directly from the recorded specification fields, but they are not benchmark results.

The absence of head-to-head data means no direct performance comparison can be made. The RX 7400's percentile rank of 17 places it in the lower portion of all GPUs. The LX 7G100's percentile rank of 50 places it at the median, but that ranking is not supported by any measured scores. The data shows a specification gap favoring the LX 7G100, yet the only verified performance numbers belong to the RX 7400.
